As a child, Violet was used by the military as a weapon because of her combat prowess. Her one friend and protector was Major Gilbert, who named the girl, taught her how to speak and write, and cared for her. But after being seriously injured in the war, losing both arms in the process, Violet is brought to the Evergarden household to recuperate. There, she trains to become an Auto Memories Doll: a person who writes letters for others, deciphering their true feelings and expressing it on paper. As Violet travels the world, she helps her clients find love and comfort through the letters she writes; but more importantly, she slowly begins to understand emotions, so that she can finally cope with what she’s done, and what she’s lost.
